§ 51.027 USERS OF THE POTW; PROHIBITED DISCHARGES.
   (A)   The following general prohibitions shall apply to all users of the POTW, whether or not a user is subject to national categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements.
   (B)   A user shall not contribute in detrimental quantities the following substances to the POTW:
      (1)   Any liquids, solids, or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious or hazardous in any other way to the POTW or to the operation of the POTW. At no time, shall two successive readings on a meter capable of reading L.E.L. (lower explosive limit) at a point at the nearest accessible point to the POTW in a sanitary sewer, at the point of discharge into the POTW, or at any point in the POTW be more than 5%, nor any single reading greater than 10%. Materials under this division include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, polychlorinated biphenyls, polybrominated biphenyls, carbides, hydrides, stoddard solvents, and sulfides;
      (2)   Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in interference with the operation of the wastewater treatment facilities, including, but not limited to, grease, garbage with particles greater than one-half inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, tar, asphalt residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes, or tumbling and deburring stones;
      (3)   Any wastewater which will cause corrosive structural damage to the POTW, but in no case wastewater having a pH less than 5.0, unless more strictly limited elsewhere in this chapter;
      (4)   Any wastewater containing incompatible pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans, cause a violation of the water quality standards of the receiving waters of the POTW, exceed the limitation set forth in a national categorical pretreatment standard (when effective) or in § 51.028 or create a public nuisance;
      (5)   Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastewaters are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into sewers for their maintenance and repair;
      (6)   In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the RCRA, SWDA, the Clean Water Act, the Toxic Substance Control Act, being 15 U.S.C. 2601 et seq, or state criteria applicable to the sludge management method being used;
      (7)   Any substance which will cause the POTW to violate its NPDES permit or the receiving water quality standards;
      (8)   Any wastewater having a temperature at the point of discharge to the POTW which will inhibit biological activity in the POTW treatment plant resulting in interference; in no case shall wastewater be introduced to the POTW which exceeds 65°C (157°F) or which exceeds 40°C (104°F) at the POTW treatment plant;
      (9)   Any pollutants, including compatible pollutants released at a flow or pollutant concentration which a user knows or has reason to know will cause interference to the POTW or will pass through the POTW;
      (10)   Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by state or federal regulations;
      (11)   Any wastewater which may contain more than 75 mg/l concentration of fat, oil, grease (FOG) or trichlortrifluoroethane extractable material;
      (12)   Any wastewater containing BOD, total solids, or suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant; provided, however, that a user may be permitted by specific, written agreement with the POTW, which agreement to discharge such BOD or TSS may provide for special charges, payments or provisions for treating and testing equipment;
      (13)   Ammonia nitrogen in amounts that would cause a violation of the water quality standards of the receiving waters of the POTW;
      (14)   Any discharge exceeding the standards established in 35 Ill. Adm. Code 307 from time to time; and
      (15)   Any slug discharged to the POTW.
   (C)   Compliance with the provisions of this section shall be required on the effective date of promulgation of this chapter.
